I just pulled this out of an RC10 I bought off ebay for parts. I think the car probably has 2 or 3 hours total time on it as it was assembled with mistakes all over it and the performance must have been terrible...Just look at the wear on the thrust bearing washer. It was pretty much seized to the shaft?! I guess I'm in the market for a new one...

The front and rear suspensions were in perfect shape and even the gold tub was only scratched lightly on the rear end...

Whats the best way to clean up scratched gold aluminum anyways???

the other side of the washers are still good. just flip'em around.

You're right I just looked at the manual I think it should be fine flipped around. The side near the diff gear shouldnt matter if it's grooved...Good call

Nope, those washers are SUPPOSED to be grooved—both of them. They aren't worn, they are machined that way. Contemporary thrust washers use races like that to keep everything aligned better, and to prevent the inner bearing race from squirming. Some very high-end import touring cars use very expensive thrust bearings and washers just like that. I had a Corally sedan that used ceramic thrusts and diff balls and were the smoothest diffs you have ever felt.


That being said, both sides should be identical and even the same size. That thrust looks like a mix of a couple of different car's parts. Those raced thrust washers didn't come around for a long time after the RC10 was out. There are many thrust bearings out there that will do the same thing for you, and are cheap. Just get a TB that has the same I.D. and you should be good to go. I would guess than any contemporary Stealth TB would work fine, but that's just a guess.


An early 6-gear thrust assembly should't be TOO tough to find, though.

I hear what you're saying but since the two peices were pretty much stuck together when i took it apart, and the washer was jammed on the shaft and was turning with the diff shaft I think it was the stock aluminum peice that was just ruined. The diff balls in the thrust washer were also stuck inside and wouldnt move. Like I said the car was built by a 10yr old or something and it wasnt pretty!!!

What I meant to say was, that washer isn't an RC10 piece at all, but it's not worn out. It didn't work because the radius path of the blue center race isn't the same as the radius path of the grooved plate. That blue center race is plastic, so anything that touches it that is spinning will melt it.

You need 2 washers and one center race for the same car to work for your thrust bearing. That one shouldn't work very well, even flipped around, because the size is wrong, and the blue center race probably was melted in the process.

Your best bet is to find a stock thrust assembly or experiment with an aftermarket one from a different tranny, like a Losi XXX (larger than a Stealth thrust).

OK yeah you're right I think that blue thrust washer is cooked too...I'll get a new set just to be sure...cheers!!!
